CLEVIS.

Application filed January 17, 1916.

To all whom it may concern:

Be it known that I, GEORGE H. METGALF, a citizen of the United States,residing at lVilkinson, in the county of Wilkinson and State ofMississippi, have invented new and useful Improvements in Clevises, ofwhich the following is a specification.

The present invention relates to clevises for plows and similar farmingimplements.

An object of the invention is to provide a clevis of simple and improvedconstruction which will permit of a vertical adjustment of the draftwithout removing any of the parts constituting the clevis when the sameis applied to the plow beam.

A further object of the invention is to produce a clevis of thecharacter described which will permit of not only a vertical adjustmentof the draft, but further retain the draft in its respective adjustedpositions.

With the above and other objects in view, the invention consists of thenovel features, details of construction, and combination of parts whichhereinafter will be more fully illustrated in the accompanying drawingand pointed out in the appended claims.-

In the accompanying drawing :Figure l is a side elevation partly insection showing the front end of a plow beam equipped with my improvedclevis; and Fig. 2 is a perspective view showing the position occupiedby the parts when the draft link is to be ad justed.

Referring more specifically to the drawing wherein like referencecharacters refer to corresponding parts in the several views theimproved clevis includes in its construction a bracket 5 of U-shapedconfiguration embodying an upper limb 6 and a lower limb 7, the limbsbeing connected with one another through the medium of a connectingportion 8. The top and bottom limbs may be described as consisting ofbars fitted upon the respective upper and lower faces of the plow beam Band stationarily mounted on the forward end thereof through the mediumof pins or bolts 9. The connecting portion 8 being also in the nature ofa bar is disposed forwardly of and vertically of the extreme forward endof the plow beam B when the clevis is in applied position as shown. Thisconnecting portion gradually increases in transverse width from theupper limb 6 toward the lower limb 7, by dis- Specification of LettersPatent.

posing the outer vertical edge 10 thereof in a downward and forwardinclined direction, the purpose of which is to enable the insertion ofthe draft link 11 within the U-shaped recess 12. The U-shaped recess 12is constructed by disposing in vertical opposed relation with theconnecting portion 8 and forwardly thereof an L-shaped draft stand ard13, said standard being integrally connected with the bracket 5 by meansof the horizontal portion of the draft standard 14. This draft standard13 has formed on its innermost surface a series of notches 15 which arearranged in vertical superposed relation one to the other and continuedaround on the side faces 16 of the standard, as indicated by thecharacter 17, whereby the draft link will be permanently held againstany slight vertical movement when the same is connected with the clevis.

The entrance to the U-shaped recess 12 is obstructed by a plate 18 andis permanently connected in obstructing relation with respect to therecess 12 through the medium of a pair of screws 19 and 19, the screw 19engaging the upper end of the connecting portion 8 while the screw 19being screwed into the upper free end of the draft standard 13. Thisplate has formed on the under surface thereof at a point substantiallymedially of its length a keeper 20 in the nature of a stout flatflexible spring bowed in a direction toward the notches 15 of the draftstandard 13 and the office of which is to retain the draft link in itsproper vertical adjusted position and prevent any accidentaldisplacement of the draft link from the draft standard 13. A furtherobject of the keeper 20 more especially owing to its resilient nature,is to permit of the removal of the draftlink 11 from one of the notchesof the draft standard and the insertion in a further notch thereofwithout the necessity of removing the plate 18.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of construction and of the methodof operation will be readily apparent to those skilled in the art towhich the invention relates, and while I have described the principlesof operation of the device together with the device which I now considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such advantages may bemade when desired as are within the scope of the appended claims.

I claim:

1. A device of the class described embodying a U-shaped bracketcomprising a vertically disposed connecting portion, an L-shaped draftstandard formed contiguous with and disposed forwardly of the connectingportion of the bracket and defining a substantially U-shaped recess, adraft link mounted in said recess, a plate closing said recess and akeeper formed integral with the plate and preventing the displacement ofthe link from said standard.

2. A device of the class described embodying a U-shaped bracketconsisting of a vertically disposed connecting portion, an

L-shaped draft standard formed contiguous v with and disposed forwardlyof the connecting portion of said bracket and having a series ofvertically alined notches, the positioning of the draft standard withrespect to the bracket defining a U-shaped recess, a draft linkpositioned in said U-shaped recess, a plate closin r ent bowed keeperformed integral with the plate and depending withinthe recess forholding the draft link in the notches of the standard and permitting ofa vertical adjustment of the link with respect to said standard.

In testimony whereof I afiix my signature in presence of two witnesses.
